norsrme AND LOADING DEVICE Application filed September aziaa'e. serialNo. 395,717.

My invention relates to improvements in hoisting and loading devices,and the object of my improvements is to supply a simple, inexpensivedevice of this class particularly adapted for loading railway gondolasor other cars, or any other receptacles as desired conveniently, andoperable by manual or other power, while being compact to employ aminimum space therefor.

This object I have successfully accomplished and examplified by themeans which are hereinafter described and claimed, and which areillustrated in the accompanying drawings, in which Fig. -1 is a frontelevation of my improved device, showing the shoot bucket in its loweredreceiving position, and Fig. 2 is a side elevation, with a part of theframe structure broken away, showing the bucket in its elevated andtilted 29 delivery position. Fig. 3 is a detail side elevation of thebucket and its bail in a receivin position.

y invention is not restricted to the pre V cise construction andarrangement of parts herein shown and described, nor to the variousdetails thereof, as the same may be modified or rearranged in variousparticulars without departing from the spirit and scope of my invention,one practical embodiment of which has been herein illustrated anddescribed without attempting to show all :of the various forms andmodifications in which my invention might be embodied.

My device includes a supporting frame Which may be rigidly fixed uponeither a permanent or a movable base as desired, and comprises thespaced inwardly channeled vertical beams 1 connected at the upper endsby a pair of spaced cross-bars 2. Between these bars a grooved sheave 13may be rotatably mounted, and said bars may project at one end andanother sheave 14 rotatably mounted between these extensions.

In the interspace of the standards 1 is positioned an open top elongatedshoot bucket whose forward closed end 3 is of greater height than theelongated delivery part 4.

the latter being open terminally. This m bucket is also preferablyshaped with its receiving end at the bottom flat to support it as inFig. 3 upon the supporting base hori zontally, the elongated shoot part'e-being directed slopingly upwardly at a desiredangle; A cross-bar 5 isfastened across the bottom of the bucket with projecting pintles 6, andlocated so that the bucket isunbalanced towardits receiving end'3/ Thenumeral-8' denotes a bail having depending members? whose terminationsare apertured to seat'the pintles 6 of the crossbar 5 tiltably. Thesemembers span the inter space of the standards 1 and are slidabl mountedin the inner channels of the stand ards to ride therein whenthe bucketis hoisted or lowered to prevent lateral rocking of the bucket. To themiddle of the bail 8 a; double-ended eye-bar or link 9 is secured by abolt or pintle 10, and its upper eye receives a loop on the flexiblecable 12 depending from and reeved upon the sheaves 13 and 14. The cablethence passes downwardly to and its end secured upon the winding-drum ofa winch 16 rotatably mounted on a fixed bracket on onestandard 1 at 15on a shaft 17. The shaft has a terminal handled crank 18 for manualoperation of the winch, a ratchetwheel 19 on the shaft releasablyengaged by a gravity pawl 20, preventing release of the cable and thebucket when the latter is raised to any position for tilting. It will'80 be understood that instead of a winch, any other means may be usedfor actuating'said cable 12, such as a motor, whether electric or usingcompressed air or otherwise.

Any desired means may also be employed 86 for the purpose of tilting thebucket to a delivery position, such as a chain 21 connected to its spoutor delivery end 4 (shown in Fig. 2), as the bucket being unbalancedtoward its receiving end is hoisted in that position, 0 and whenunloaded and the pawl 20 tripped to release it, the bucket tilts backunder the influence of the greater weight of its receiving end tb itsnormal position shown in Fig. 3.

The numeral 11 denotes a pair of bent bars fastened to the oppositeparts of the bail cross member 8 having their depending and forwardlyhooked ends over the bucket. When the bucket as shown in Fig. 2 is inits tilted position to deliver its contents, the

, tiltedto discharge its contents, and also to v hooked terminations ofthe stops 11 engage the forward inner Wall of the bucket to limit itsfarther tilting.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

A device of the character described, comprising a supporting structurewith spaced vertical guide standards, a shoot bucket, hoisting means forraising and lowering said bucket including a bail "connected there topivotally at one side of the buckets center of gravity to permit it tonornially tilt toward its receiving end, said means being slidable uponsaid standards top'revent later'-' al rocking of the'bucket, and spacedhooked p n g fi s, upon, thejba l a p d t engagethe bucket rear wall When the latter is li rnit the tilting position of the bucket its normalreceiving positionf w 'In'testimo'ny vvhereofl aifix my signature.
